Update ARB Subscription Status?

[ajzeffer]

In the  ARBUpdateSubscription function I don't see any referrence to being able to update status (eg "active" , "suspended"). Is that not possible?

Something like this? From the ARB.markdown file in the doc folder of the SDK:

$cancellation = new AuthorizeNetARB;
$cancel_response = $cancellation->cancelSubscription($subscription_id);
